Essential actions to mitigate the food crisis, stabilize supply and transition to greater agrifood system resilience

Written by Rodrigo Ordóñez on July 19, 2022. Posted in Press releases.

As the Russia-Ukraine war continues to degrade global food security, a new analysis lays out concrete actions that governments and investors must do now to mitigate near-term food security risks and stabilize wheat supplies, while transitioning toward long-term resilience.

The guidance, published in Nature Food by scientists from the International Maize and Wheat Improvement Center (CIMMYT) and partners, lays out short-, medium- and long-term steps to respond to the global food crisis and ultimately lead to a more resilient global agrifood system.

“The Russia-Ukraine war will impact global food security over months — if not years,” said CIMMYT Global Wheat Program Director and lead author Alison Bentley. “We now need to move beyond defining the problem to implementing practical actions to ensure stable supply, safeguard the livelihoods of millions of vulnerable people and bring resilience to our global agrifood system.”

The war in Ukraine and trade sanctions against Russia are triggering a level of volatility that could easily overwhelm existing mitigation mechanisms. More than 2.5 billion people worldwide consume wheat-based foods; those in lower- to middle-income countries dependent on imports from Russia and Ukraine are particularly affected. Some of the world’s poorest countries, such as Bangladesh, Sudan and Yemen, rely heavily on Russian and Ukrainian wheat. Given the highly interconnected nature of contemporary agrifood systems, few will remain unaffected by this new global food shock.

Mitigate the immediate crisis

The first priority, according to the authors, is to mitigate the immediate crisis by boosting wheat production in existing high- and low-productivity areas, ensuring grain access and blending wheat flour with other low-cost cereals. Bundled agronomic and breeding improvements and sustainable farming practices can reduce dependence on imported grain and fertilizer, while coordinated, multilateral policies can help conserve grain stocks for human consumption and avert trade restrictions.

Increase the resilience of wheat supply

In the medium term, the authors emphasized the need to increase the local, regional, and global resilience of the wheat supply. This can be done by expanding production within agro-ecological boundaries, supporting national wheat self-sufficiency and providing technical assistance, to increase the production of high-yielding disease-resistant wheat and to mainstream capacity for pest and disease monitoring.

Transition to system-level resilience

Finally, to reach crucially needed resilience in the world’s agrifood system, long-term measures must be taken that encompass agroecosystem diversity, address gender disparities in agriculture and rural communities and sustain increased investment in a holistic, agrifood transition.

“The current global food crisis underscores and compounds existing inequalities in our global food system,” Bentley said. “A transition to agrifood system resilience requires us to urgently balance global food supply needs with the multi-layered challenges of climate change, achieving gender equity, nutritional sufficiency and livelihood security.”

New CGIAR Initiative to catalyze resilient agrifood systems in eastern and southern Africa

Written by Rodrigo Ordóñez on May 9, 2022. Posted in News.

Partners of CGIAR’s new regional integrated Initiative in eastern and southern Africa held a kick-off meeting in Nairobi on March 2–3, 2022. Eighty-five people participated, including national agricultural research extension programs, government representatives, private sector actors, funders and national and regional agricultural research and development organizations.

Entitled Ukama Ustawi, the Initiative aims to support climate-smart agriculture and livelihoods in 12 countries in eastern and southern Africa: Kenya, Zambia, Ethiopia and Zimbabwe (in Phase 1); Malawi, Rwanda, Tanzania and Uganda (in Phase 2); and Eswatini, Madagascar, Mozambique and South Africa (in Phase 3).

The Initiative aims to help millions of smallholders intensify, diversify and de-risk maize-mixed farming through improved extension services, institutional capacity strengthening, targeted farm management bundles, policy support, enterprise development and private investment.

Ukama Ustawi is a bilingual word derived from the Shona and Swahili languages. In Shona, Ukama refers to partnerships, and in Swahili, Ustawi means well-being and development. Together, they resemble the vision for the Initiative to achieve system-level development through innovative partnerships.

The meeting brought together partners to get to know each other, understand roles and responsibilities, identify priorities for 2022, and review the cross-cutting programmatic underpinnings of Ukama Ustawi — including gender and social inclusion, capacity strengthening and learning.

Baitsi Podisi, representing the Centre for Coordination of Agricultural Research and Development for Southern Africa (CCARDESA), said he is excited to be part of the Initiative: “CCARDESA, in its cooperation and coordination mandate, can learn a lot from CGIAR in restructuring to respond to the changing times.” Podisi supported the partnership with CGIAR in the Initiative’s embedded approach to policy dialogue, working with partners such as CCARDESA, the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) and the Food, Agriculture and Natural Resources Policy Analysis Network (FANRPAN).

Similarly, FANRPAN’s Francis Hale emphasized the need not to re-invent the wheel but to work with partners who already have a convening power, to advance the policy agenda for diversification and sustainable intensification.

What were key issues discussed?

One of the features of Ukama Ustawi is the use of four interconnected platforms: a scaling hub, a policy hub, an accelerator program and a learning platform. These will provide spaces for exchange and learning with partners across all CGIAR Initiatives in the region. Partners conducted a series of ‘fishbowl’ interactions across work packages to review the planned activities and provide a clearer understanding of deliverables, identify synergies, potential overlaps, common partners and countries, and set timelines.

The Initiative will work with innovative multimedia platforms to change knowledge, attitudes and practices of millions of farmers in eastern and southern Africa. One key partner in this area is the Shamba Shape Up TV show and the iShamba digital platform. Sophie Rottman, Producer of Shamba Shape Up, said she is looking forward to the work with Initiative partners, that will help expand the show to Uganda and Zambia.

Jean Claude Rubyogo, representing the Pan-Africa Bean Research Alliance (PABRA) said: “It is time we move away from CGIAR-initiated to country-initiated development activities. This is what Ukama Ustawi is all about”.

Martin Kropff, Global Director of Resilient Agrifood Systems at CGIAR, explained CGIAR’s regional integrated initiatives are designed to respond to national/regional demands. “The initiatives will start by working with partners to assess the food and nutritional challenges in the region, and tackle them by bringing in innovative solutions.”

The event was concluded by agreeing on the implementation of the inception phase of the Ukama Ustawi Initiative, and follow-on discussions to finalize key activities in 2022.

Reduced cropping intensity in India

Written by Rodrigo Ordóñez on April 1, 2021. Posted in In the media.

Groundwater is essential for Indian agriculture and rural livelihoods, but groundwater levels are declining. Simply providing canal irrigation as a substitute irrigation source will likely not be enough to maintain current production levels.

Global malnutrition: Why cereal grains could provide an answer

Groundwater depletion in India could reduce winter cropped acreage significantly in years ahead

Written by Rodrigo Ordóñez on February 24, 2021. Posted in Press releases.

India is the world’s second-largest producer of wheat and rice and is home to more than 600 million farmers. The country has achieved impressive food-production gains since the 1960s, due in part to an increased reliance on irrigation wells, which allowed Indian farmers to expand production into the mostly dry winter and summer seasons.

But those gains have come at a cost: The country that produces 10% of the world’s crops is now the world’s largest consumer of groundwater, and aquifers are rapidly becoming depleted across much of India. Indian government officials have suggested that switching from groundwater-depleting wells to irrigation canals, which divert surface water from lakes and rivers, is one way to overcome projected shortfalls.

In a study published in the journal Science Advances, scientists conclude that a switch to canal irrigation will not fully compensate for the expected loss of groundwater in Indian agriculture.

The authors estimate that if Indian farmers lose all access to groundwater in overexploited regions, and if that irrigation water is not replaced with water from other sources, then winter cropped acreage could be reduced by up to 20% nationwide. However, that scenario seems highly unlikely and was included in the study only as an upper-bound estimate.

It seems more likely that any future groundwater shortfalls would be at least partially offset by increases in canal irrigation. But even if all Indian regions currently using depleted groundwater switch to canal irrigation, winter cropped acreage could still decline by 7% nationwide and by 24% in the most severely affected locations, according to the researchers.

Water alternatives needed

“Our results highlight the critical importance of groundwater for Indian agriculture and rural livelihoods, and we were able to show that simply providing canal irrigation as a substitute irrigation source will likely not be enough to maintain current production levels in the face of groundwater depletion,” said study lead author Meha Jain, an assistant professor at the University of Michigan’s School for Environment and Sustainability.

“We need coordinated efforts to solve this water availability and food security issue, which should be supported by science-led policy decisions on what strategies and technology solutions to scale out to improve irrigation efficiency,” said co-author Balwinder Singh, a Cropping Systems Simulation Modeler at the International Maize and Wheat Improvement Center (CIMMYT).

The study analyzed high-resolution satellite imagery and village-level census data and focused on winter cropped acreage. While nearly all Indian farmers plant crops during the monsoon to take advantage of seasonal rains, winter agriculture is mainly reliant on groundwater irrigation and now accounts for 44% of the country’s annual cropped acreage for food grains.

“These findings suggest that other adaptation strategies, in addition to canal expansion, are needed to cope with ongoing groundwater losses,” Jain said.

The possibilities include switching from winter rice to less water-intensive cereals, increased adoption of sprinklers and drip irrigation to conserve water in the fields, and policies to increase the efficiency of irrigation canals.

While groundwater depletion is becoming a global threat to food security, and the extent of current and projected groundwater depletion are well documented, the potential impacts on food production remain poorly quantified. The study is the first to use high-resolution empirical data, including census data about the irrigation methods used in more than 500,000 Indian villages, to estimate the crop production losses that may occur when overexploited groundwater is lost.

“Understanding the complex relationship between food security and water availability is crucial as we prepare for future rainfall variability due to global climate change,” said co-author Gillian Galford of the University of Vermont.

The proliferation of deep (>30 meters) irrigation wells called tube wells since the 1960s has enabled Indian farmers to increase the number of seasons when crops are planted in a given year. This increase in “cropping intensity” is credited for much of the country’s food-production gains.

The map on the right (B) shows projected winter cropped acreage losses if groundwater irrigation is replaced with canals, using national-level regression coefficients. (Graph: Jain et al. in Science Advances 2021)

Big data for food security

The researchers used satellite data to measure Indian winter cropped area, a key determinant of cropping intensity. They then linked the satellite data to census information about the three main types of irrigation infrastructure in India: shallow “dug wells,” deeper tube wells and canals that divert surface water.

Linking the two datasets allowed them to determine the relative efficacy of each irrigation method. That, in turn, enabled them to estimate potential future acreage losses and the ability of canal expansion to fill the gap.

The study’s worst-case scenario found that winter cropped area could decrease by up to 20% nationwide and by 68% in the most severely affected regions, if farmers lose all access to groundwater and if that irrigation water is not replaced from another source. The expected losses would largely occur in northwest and central India, according to the study.

The researchers also found that increased distance from existing irrigation canals is strongly associated with decreased acreage planted with winter crops. In the future, a greater reliance on canals could increase inequities related to irrigation access, according to the authors.

“This suggests that while canals may be a viable form of irrigation for those who live near canals, they may lead to more unequal access to irrigation across villages compared to wells, with negative impacts for those who live farther from canals,” the authors wrote.

In addition, the lakes and rivers that feed irrigation canals rise and fall in response to rainfall variability, unlike deep groundwater wells. So, a greater reliance on canal irrigation in the future would result in increased sensitivity to year-to-year precipitation fluctuations, as well as any long-term trends due to human-caused climate change.

The authors of the Science Advances study, in addition to Jain and Galford, are Ram Fishman of Tel Aviv University; Pinki Mondal of the University of Delaware; Nishan Bhattarai of the U-M School for Environment and Sustainability; Shahid Naeem, Upmanu Lall and Ruth DeFries of Columbia University; and Balwinder Singh of the International Maize and Wheat Improvement Center (CIMMYT).

The work was funded by a NASA New Investigator Award to Jain and two NASA Land Cover and Land Use Change grants, one awarded to R.S. DeFries and one to Jain.

“Happy Seeder” saves farmers money over burning straw, new study in India shows

Written by Mike Listman on December 10, 2020. Posted in News.

Compared to conventional tillage practices, sowing wheat directly into just-harvested rice fields without burning or removing straw or other residues will not only reduce pollution in New Delhi and other parts of northern India, but will save over $130 per hectare in farmer expenses, lessen irrigation needs by as much as 25%, and allow early planting of wheat to avoid yield-reducing heat stress, according to a new study published in the International Journal of Agricultural Sustainability.

The practice requires use of a tractor-mounted implement that opens grooves in the soil, drops in wheat seed and fertilizer, and covers the seeded row, all in one pass. This contrasts with the typical method for planting wheat after rice, which involves first burning rice residues, followed by multiple tractor passes to plow, harrow, plank, and sow, according to Harminder S. Sidhu, principal research engineer at the Borlaug Institute for South Asia (BISA) and a co-author of the study.

“There are already some 11,000 of these specialized no-till implements, known as the Happy Seeder, in operation across northern India,” said Sidhu, who with other researchers helped develop, test and refine the implement over 15 years. “In addition to sowing, the Happy Seeder shreds and clears rice residues from the seeder path and deposits them back onto the seeded row as a protective mulch.”

Covering some 13.5 million hectares, the Indo-Gangetic Plain stretches across Bangladesh, India, Nepal and Pakistan and constitutes South Asia’s breadbasket. In India, the northwestern state of Punjab alone produces nearly a third of the country’s rice and wheat.

Some 2.5 million farmers in northern India practice rice-wheat cropping and most burn their rice straw — an estimated 23 million tons of it — after rice harvest, to clear fields for sowing wheat. Straw removal and burning degrades soil fertility and creates a noxious cloud that affects the livelihoods and health of millions in cities and villages downwind. Air pollution is the second leading contributor to disease in India, and studies attribute some 66,000 deaths yearly to breathing in airborne nano-particles produced by agricultural burning.

The central and state governments in northwestern India, as well as universities and think-tanks, have put forth strategies to curtail burning that include conservation tillage technologies such as use of the Happy Seeder. Subsidies for no-burn farming, as well as state directives and fines for straw burning, are in place and extension agencies are promoting no-burn alternatives.

As an aid for policy makers and development practitioners, the present study applied econometrics to compare conventional and zero-tillage in terms of yield, input levels and implications for rice residue burning. The study also compared use of the Happy Seeder versus a simple zero-tillage drill with no straw shredder. Participants included more than 1,000 farm households in 52 villages, encompassing 561 users of conventional tillage, 226 users of simple zero-tillage seeding implements, and 234 Happy Seeder users.

They found that only the Happy Seeder was able to sow wheat directly into large amounts of rice residues, with significant savings for farmers and equal or slightly better wheat yields, over conventional tillage. The Happy Seeder also saves time and water.

“Given the benefits of sowing wheat using the Happy Seeder against the tremendous health and environmental costs of residue burning, the reduction or elimination of straw burning should be pushed forward immediately,” said P.P. Krishnapriya, research scientist at the Sanford School of Public Policy, Duke University, and a co-author of the article. “Investments in social marketing and policies that foster the use of the Happy Seeders, including significant subsidies to purchase these machines, must be accompanied by stricter enforcement of the existing ban on residue burning.”

The study also found that the information sources most widely-available to farmers are currently geared towards conventional agricultural practices, but farmers who use the internet for agricultural information are more likely to be aware of the Happy Seeder.

“Awareness raising campaigns should use both conventional and novel channels,” said Priya Shyamsundar, lead economist at the Nature Conservancy (TNC) and co-author of the article. “As with any innovation that differs signiﬁcantly from current practices, social and behavioral levers such as frontline demonstrations, good champions, and peer-to-peer networking and training are critical.”

In addition, rather than having most individual farmers own a Happy Seeder — a highly-specialized implement whose cost of $1,900 may be prohibitive for many — researchers are instead promoting the idea of farmers hiring direct-sowing services from larger farmers or other people able to purchase a Happy Seeder and make a business of operating it, explained Alwin Keil, a senior agricultural economist with the International Maize and Wheat Improvement Center (CIMMYT) and lead author of the new study.

“We are extremely grateful to the Indian Council of Agricultural Research (ICAR), the Nature Conservancy, and the CGIAR Research Program on Wheat Agri-Food Systems (WHEAT), who supported our research,” said Keil.

New publications: COVID-19 induced economic loss and ensuring food security for vulnerable groups

Written by Emma Orchardson on October 29, 2020. Posted in Publications.

At present, nearly half of the world’s population is under some form of government restriction to curb the spread of COVID-19. In Bangladesh, in the wake of five deaths and 48 infections early in the year, the government imposed a nationwide lockdown between March 24 and May 30, 2020. Until April 17, 38 of the country’s 64 districts were under complete lockdown.

“While this lockdown restricted the spread of the disease, in the absence of effective support, it can generate severe food and nutrition insecurity for daily wage-based workers,” says Khondoker Mottaleb, an agricultural economist based at the International Maize and Wheat Improvement Center (CIMMYT).

Of the 61 million people who make up Bangladesh’s employed labor force, nearly 35% are paid daily. In a new study published in PLOS ONE, Mottaleb examines the food security and welfare impacts of the lockdowns on these daily-wage workers — in both farm and non-farm sectors — who are comparatively more resource-poor in terms of land ownership and education, and therefore likely to be hit hardest by a loss in earnings.

Using information from 50,000 economically active workers in Bangladesh, collected by the Bangladesh Bureau of Statistics (BBS), the study quantifies the economic losses from the COVID-19 lockdowns based on daily-wage workers’ lost earnings and estimates the minimum compensation packages needed to ensure their minimum food security during the lockdown period.

Using the estimated daily wage earnings, the authors estimate that a one-day, complete lockdown generates an economic loss equivalent to $64.2 million. After assessing the daily per capita food expenditure for farm and non-farm households, the study estimates the need for a minimum compensation package of around $1 per day per household to ensure minimum food security for the daily wage-based worker households.

In May 2020, the Government of Bangladesh announced the provision of approximately $24 per month to two million households, half of whom will receive additional food provision. While this amount is in line with Mottaleb’s findings, he stresses than this minimum support package is only suitable for the short-term, and that in the event of a prolonged lockdown period it will be necessary to consider additional support for other household costs such as clothing, medicine and education.

“Without effective support programs, the implementation of a strict lockdown for a long time may be very difficult, if poor households are forced to come out to search for work, money and food,” explains Mottaleb. “In the event of a very strict lockdown scenario, the government should consider issuing movement passes to persons and carriers of agricultural input and output to support smallholder agriculture, wage workers and agricultural value chains.”

Against the grain: New paper reveals the overlooked health benefits of maize and wheat

Written by Mary Donovan on October 12, 2020. Posted in Press releases.

Cereal crops like maize and wheat deserve greater consideration as part of a healthy, nutritious diet, according to the authors of a new paper.

A review of agri-nutrition research and dietary guidance found that the potential health benefits provided by cereals were often overlooked or undervalued as part of nutritious diets, including their role in reducing non-communicable diseases such as heart disease and diabetes.

The study identified two key explanations for the oversight. The first is that many cereal crops with varying nutritional qualities are indiscriminately grouped under the broad category of “staples.”

A second problem lies in the fact that cereals are usually considered to be a major source of dietary energy alone. However, reducing nutritional attributes to macro- and micro-nutrients misses other beneficial elements of cereals known as “bioactive food components.” These include carotenoids, flavonoids, and polyphenols, and compounds that comprise dietary fiber.

“Most whole grain cereals provide differing amounts of proteins, fats, minerals and vitamins, in addition to being important sources of dietary energy,” said Jason Donovan, a senior economist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of the paper published in Food Policy.

“Only relative to other ‘nutrient-rich’ foodstuffs can cereals be described as ‘nutrient-poor’.”

In the paper, entitled Agri-nutrition research: Revisiting the contribution of maize and wheat to human nutrition and health, the authors called on researchers and policymakers to embrace the multiple dietary components of cereals in addressing under- and over-nutrition, micronutrient deficiencies and the growing global problem of non-communicable diseases.

“Through increasing the availability of, and access to, healthy foods derived from cereals, we can better address the growing triple burden of malnutrition that many countries are facing,” said Olaf Erenstein, co-author and director of CIMMYT’s Socioeconomics program.

“To feed the world within planetary boundaries, current intakes of whole grain foods should more than double and address tricky issues like the current over-processing, to make the most of the nutrition potential of maize and wheat.”

While some carbohydrates can create a glycemic response that has negative effects on diabetes and obesity, dietary fiber in cereals comprises carbohydrates that are fermented in the large intestine with largely positive metabolic and health effects.

In addition, the naturally-occurring compounds found in maize and wheat can be enhanced through conventional breeding, genomic selection and bio- and industrial-fortification to offer enriched levels of beneficial components.

For example, scientists at CIMMYT have worked on new maize and wheat varieties with additional levels of vitamin A and zinc to help address some of the nutritional deficiencies found worldwide. Researchers are also improving how cereals are produced, processed, and stored to increase productivity and improve food safety while maintaining their nutritional benefits.

One of challenges in maximizing the nutritional benefit of cereal-based foods in diets is that the processing of grains often causes substantial losses of essential vitamins and minerals. Meanwhile, manufacturing industries create ultra-processed foods that often contain noxious qualities and components, which contribute directly to the significant and increasing global health and economic costs of non-communicable diseases.

“If we are to end hunger by delivering healthy, diverse and nutritional diets in the next decade, we need a broader and more nuanced understanding of the nutritional and health-promoting value of diverse foods, including cereals,” added Nigel Poole, co-author and Professor of International Development at SOAS University, London.

“Cereals and so-called ‘nutrient-rich’ foods are complementary in agri-nutrition, both of which require additional research, resources and attention so that one does not replace the other.”

Breaking Ground: Jordan Chamberlin avidly explores the changing landscapes of Africa

Written by Jérôme Bossuet on October 1, 2020. Posted in Features.

Sub-Saharan Africa is undergoing important transformations, including climate change, population growth, urbanization and migration flows, and growth in digital technologies. What can we say about the likely development trajectories that African rural economies are on, and the implications for poor farming households? These are central questions for Jordan Chamberlin, an economist at the International Maize and Wheat Improvement Center (CIMMYT) in Kenya.

Chamberlin’s desk is covered with screens teeming with numbers, complex mathematical equations, lines of code and aerial views of African landscapes. He combines traditional microeconomic analysis with geospatial modelling skills to study some of the ways in which rural transformations are occurring. In this era of big data, he examines the wealth of spatial and socioeconomic datasets to explore the relationships between drivers of change and smallholder welfare, sometimes revealing surprising insights on how rural communities in Africa are evolving.

“Are commercial farms good or bad for neighboring smallholder farmers? Which households can benefit from the rapidly evolving rural land markets in Africa? What drives migration between rural areas? These are some examples of the complex but increasingly important questions that inform how we understand the evolution of agri-food systems in developing countries,” Chamberlin explains. “Fortunately, we also increasingly have access to new data that helps us explore these issues.”

In addition to household survey datasets — the bread and butter of applied social scientists — today’s researchers are also able to draw on an ever-expanding set of geospatial data that helps us to better contextualize the decisions smallholder farmers make.

He cites current work, which seeks to understand input adoption behaviors through better measurement of the biophysical and marketing contexts in which small farms operate. “Evidence suggests that low use rates of inorganic fertilizer by smallholders is due in part to poor expected returns on such investments,” he explains, “which are the result of site-specific agronomic responses, rainfall uncertainty, variation in input-output price ratios, and other factors.”

We are increasingly able to control for such factors explicitly: one of Chamberlin’s recent papers shows the importance of soil organic carbon for location-specific economic returns to fertilizer investments in Tanzania. “After all, farmers do not care about yields for yields’ sake — they make agronomic investments on the basis of how those investments affect their economic welfare.”

Better data and models may help to explain why farmers sometimes do not adopt technologies that we generally think of as profitable. A related strand of his research seeks to better model the spatial distribution of rural market prices.

A spatial economist’s journey on Earth

Ever since his experience as a Peace Corps volunteer in Paraguay, where he worked as a beekeeping specialist, Chamberlin knew he wanted to spend his professional life working with smallholder farmers. He wanted to better understand how rural development takes place, and how policies and investments can help rural households to improve their welfare.

In pursuit of these interests, his academic journey took him from anthropology to quantitative geography, before leading him to agricultural economics. “While my fundamental interest in rural development has not changed, the analytical tools I have preferred have evolved over the years, and my training reflects that evolution,” he says.

Along with his research interests, he has always been passionate about working with institutions within the countries where his research has focused. While working with the International Food Policy Research Institute (IFPRI) in Ethiopia, he helped establish a policy-oriented GIS lab at the Ethiopian Development Research Institute (EDRI). Years later, as part of his work with Michigan State University, he served as director of capacity building at the Indaba Agricultural Policy Research Institute (IAPRI), a not-for-profit Zambian research organization. He continues to serve as an external advisor on PhD committees, and considers mentorship a key part of his professional commitments.

He joined CIMMYT at the Ethiopia office in 2015 as spatial economist, part of the foresight and ex ante group of the Socioeconomics program.

As part of his research portfolio, he explores the role of new technologies, data sources and extension methods in the scaling of production technologies. Under the Taking Maize Agronomy to Scale in Africa (TAMASA) project, one area he has been working on is how we may better design location-specific agronomic advisory tools. Working with the Nutrient Expert tool, developed by the African Plant Nutrition Institute (APNI), he and his research team have conducted randomized control trials in Ethiopia and Nigeria to evaluate the impacts of such decision-support tools on farmer investments and productivity outcomes. They found that such tools appear to contribute to productivity gains, although tool design matters — for example, Nigerian farmers were more likely to take up site-specific agronomic recommendations when such information was accompanied by information about uncertainty of financial returns.

Creative rethinking

While Chamberlin’s research portfolio is diverse, one commonality is the drive to use new data and tools to better guide how development resources are allocated.

“Given the scarcity of resources available to governments and their partners, it is important to have sound empirical foundations for the allocation of these resources. Within CIMMYT, I see my role as part of a multidisciplinary team whose goal is to generate such empirical guidance,” he says.

This research also contributes to better design of agricultural development policies.

“Even though many of the research topics that my team addresses are not traditional areas of emphasis within CIMMYT’s socioeconomic work, I hope that we are demonstrating the value of broad thinking about development questions, which are of fundamental importance to one of our core constituencies: the small farmers of the region’s maize and wheat-based farming systems.”

Genome editing, gene drives, and synthetic biology: Will they contribute to disease-resistant crops, and who will benefit?

Written by Mike Listman on September 3, 2019. Posted in News.

Ensuring the access of small-scale farmers to products and potential benefits from genetic engineering (GE) technologies for agriculture will require concerted investment and research by public institutions worldwide and particularly in low- and middle-income countries.

This was a key conclusion of a new review paper describing cutting-edge GE applications that offer exciting options to enhance the disease and pest resistance of important food crops and the ecological sustainability of cropping systems.

The technologies include gene editing (site-specific changes to DNA in a genome), gene drives (greatly enhancing or reducing frequency of genes that affect insect or pathogen reproduction), and synthetic biology (re-design or construction of biological devices, for example chromosomes or organelles).

Authored by international experts in policy, socioeconomics, and biological science, the new paper outlines potential uses of the technologies, particularly to address problems that affect resource-poor farmers or consumers, such as the viruses that attack cassava, the Striga weed that is a parasite of maize, or the fungal pathogen of groundnut that produces deadly toxins.

A weak capacity for research and development in many countries, combined with a small and declining public investment, raises questions about those nations’ ability to develop and deliver high-quality GE technologies or realize their benefits.

“The concern is that farmers not served by leading companies, who are developing the technologies, will be unable to obtain new, resistant crop varieties or other products of these technologies,” said Kevin Pixley, director of the genetic resources program of the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new paper.

The technologies have already proven effective for controlling bacterial, fungal, and viral plant pathogens, as well as insects that transmit them. For example, GE approaches to control cassava brown streak disease and cassava bacterial blight—for which there are few or no known sources of resistance in cassava itself—appear on track to produce resistant versions of cassava.

Future gene drive technologies that can be kept within specific areas and reversed if needed may offer ways to control insects that carry plant diseases or weeds that damage crops, and synthetic biology could someday create plants that are immune to invading viruses.

“The private sector is likely to invest mainly in major crops and major traits that will bring them profits, so work on minor, perennial, clonal, or staple food crops of lower-income countries may suffer,” said José Falck-Zepeda, senior research fellow and leader of the policy team in the program for biosafety systems of the International Food Policy Research Institute (IFPRI) and a co-author of the review paper.

Many countries are still deciding whether and how they will regulate new GE products. The new paper explains how key factors including the cost and complexity of complying with biosafety regulations will shape the potential distribution of the technologies and products, determining which institutions undertake the related research and, as a result, which traits and crops are studied.

Civil society concerns regarding GE technologies and how or by whom they are deployed add important considerations to the complex questions surrounding the use of GE products.

“Realizing the potential of GE crops will require investments and policies for research, intellectual property regimes, and regulatory frameworks,” say the authors, “and societies must also address legitimate concerns about their responsible stewardship, agroecological sustainability, and equitable access to associated benefits.”
